Camped at site 5 with an E-Pro 19FD.  Sites are back in and have well maintained level sites of crushed gravel.  The first time I haven't had to level the trailer side to side. Water and Electrical hookups well maintained.  Site is all gravel.

Walking to the Columbia River and viewing the petroglyphs is an enjoyable stroll.  Restrooms and Showers are well maintained and clean.

Watch out for the incredible amount of goose poop.  There was an area roped off so as not to disturb a nesting Eagle that could be viewed with the naked eye.

If your a fan of trains you are right next to the BNSF tracks.  

Best Park Hosts that I have ever meet.  Very knowledgeable on local sites and and things to do/visit.  They are constantly busy keeping the park in order.
